During the past season fifty acres of scrub oak lands were underphinted wilh 

 white pine. The older plantations are thriving and some very interesting coni- 

 ])arisons in the rate of growth of the various species can he shown. 



Very little denuind has been made l)y the public for planting material during 

 I lie past season. This lack of demand is ])robably caused by abnornud labour 

 conditions. During this season we shipped lOO.coo plants to other parts of the 

 Province for experimental plantnig. ' 



A prelimiiuiry survey of the sand dunes in Priiu-e Edward County was made 

 uitli a view to reforestation. This sand I'ovmation presents a different prol)lem 

 from that in Norfolk. Tlie formation is made up of sand ridges witli very little 

 vegetation left. These ridges are shifting, forming dunes Avhich will be more 

 difficult to control than the Idowing sand on k'vel areas. 



Ill, Trei-: Diseases. 



The Avork on White Pine Blister Rust has licen followed up this season along 

 lines indicated in previous reports. 



As indicated last season the stage of the disease found on IJibes (currants 

 and gooseberries) is found throughout the older portion of the Province. Its 

 distribution is so widespread that no methods of general eradication seem ^ssible. 

 Scouting done in the liainy Eiver, Sudbury and Temiskaming Districts failed 

 lo show that the disease had spread into these regions. It was found at points 

 in IJenfrew County and it is evident that it will gradually work northward 

 unless some means of eradication are developed. 



It has been found that white pine is ])raetically safe if the Eibes are eradicated 

 within a few hundred yards of the pine. Following upon this theory we have 

 >tarted the work of eradicating all Eibes from the Provincial Forest Station in 

 Xorfolk Avhere- white pine is one of the important species. This seems feasilde 

 where isolated Idocks of white pine exist as in woodlots of Southern Ontario. 



This season's results in eradicating Eibes on the Norfolk area will impress 

 u])on the layman the difficulty of carrying out this policy in our wild lands to 

 the north.
